Synthesis and Characterization of (3-naphthalene-1-yl)-dithiourea- ethylene and Preliminary Binding Study with Metal Cations.

A new thiourea derivative, (3-naphthalene-1-yl)-di-thiourea-ethylene has been synthesized by refluxing a mixture of ethylenediamine and 1-naphthyl isothiocyanate. The product was characterized by ¹H and 13C Nuclear Magnetic Resonance and FT-Infrared spectroscopic techniques. The molecular weight of the compound was determined by Mass Spectrometry. Preliminary binding study of the thiourea with metal cations shows good affinity towards Fe2+, Hg2+, Ag+, Cu2+. [ABSTRACT FROM AUTHOR]
